Test time! Cam Sensor unplugged
« on: June 08 2018, 06:58:35 PM »
Will some of you guys that have large injectors do me a favor?  Crank your car up and unplug the cam sensor connector plug.

I have always thought that the car should flip into batch mode and keep right on running as if nothing had really happened.  Not every ones' car does so, however.  Now, John Spina just told me that the car assumes it has stock injectors when it flips over so cars with big injectors may run badly because they are running very rich.

My cars have SD chips and that may be a difference maker.

So go pop the connector and see if you will-if you have larger injectors.

A lot of broken parts does not make you a racer; it makes you a slow learner.

Does it use the analog "programming" of the CALPACK? then it would assume stock.

Did that for years with blue tops (36#s). Best was an 11.28 @ 122 in a TTA. Melissa ran 11.4s in a Buick.

Hey Steve,


Just for the record...60 lb injectors, 38 psi on the FPR. Runs worse with the cam sensor unplugged. Not running SD.
